I am trying to setup MRA .
But its unsuccessful. and getting the error in the status > unified communication
I am not using any TLS and have not uploaded any certificate since i am not using a secure deployment.
any help in troubleshooting appreciated.
Solved! Go to Solution.
so that means your _collab-edge._tls.domain.com is working fine.
first, check 5222 port is open from external network
use this site to check firewall ports http://www.yougetsignal.com/tools/open-ports/
Make sure your IMP is active in expressway-C.
Important Note: Define your internal as well as external domain in expressway-c and enable cucm and IMP registration for the public domain. it seems you are using the only internal domain in expressway-c no issues define external domain also inside the domains option.
if a still issue is there then delete IMP and CUCM servers and add again.
Make sure you are using Public CA or Open SSL because
Best practice is to use external public CA because open SSL will not help you to register your IP phone, Dx series, telepresence endpoints over the MRA.
Note: while signing CSR keep in mind expressway will not support wildcard certificate
I tired troubleshooting the issue today and this time i am getting the " cannot communicate with server error " from internet.
The error is not consistent last time when i checked it was giving username and password invalid error.
I am attaching a fresh log from express c,e and jabber PRT
If you want to resolve
I can see in logs _collab-edge._tls.domain.com is not resolving from
try below commands from your side.
1) SRV Records not working externally >
Default Server: Cisco00447
> set type=srv
*** No Service location (SRV) records available for _collab-edge._tls.sddclab.com
2) No Public CA valid certificate installed in expressway-
check SRV records because traffic is not reaching expressway-e
The domain you are looking is my internal domain
my external domain is uc.itp-inc.com
